"Computers have to work the way people expect and not the other way round. I want everything can you touch on the screen to operate like objects in the real world do.

"In the future, we will look at the gestures of your entire body, facial expressions, arms, all of the fingers that you have, and you're going to have screens not just in the palm of your hand, but all around you," he said.

Duarte promised that Google would never clamp down on the user's ability customize Android on their phones.
